[PATCH] ARM: <asm/floppy.h>: fix build with sparse IRQs

[Ethan Nelson-Moore]

If sparse IRQs are enabled, <mach/irqs.h> is no longer implicitly
included when building the floppy driver. This causes the build to fail
because IRQ_FLOPPYDISK, which is used by <asm/floppy.h>, is no longer
defined. Fix this issue by including <mach/irqs.h> from <asm/floppy.h>.
The only machines that select ARCH_MAY_HAVE_PC_FDC (and thus use
<asm/floppy.h>) are footbridge and rpc, both of which have
<mach/irqs.h>.
